Vof South Carolina, have invented certain new and useful improvements in Stoves, of which the following is a specification.

`.The object of the present invention is to provide an improved trash burning or wood burning stove having various novel features of construction rendering itv more convenient and adaptable in use than stoves of this class heretofore designed or suggested. More particularly stated, the objects of the invention are, to provide a stove of this character having draft openings atk the top and bottom so that the draft may be directed against the burning fuel laterally or downwardly from the top of the stove, it being optional with the user to direct the draft in either direction; which is made in sections conveniently secured together so that any section may be replaced when damaged through being burned out, or for any other cause, and in which, by constructing the stove with a hopper shapedv ash or lire supporting bottom the operator is enabled to quickly and conveniently remove the ashes and debris from the combustion chainber by simply opening a door in the bottom through which the ashes fall.

One embodiment of the invention is described below and illustrated in the accord panying drawings in which:

Figure 1 is a top view ofthe stove, kthe lidl of the fuel. inlet opening` having been removed Figure 2 is a section on the line 2 2 of Figure 3;

Figure 3 is a section on the line 3-3 of Figure 1;

Figure i is a section on the line 4.-!1 of Figure 1; and

Figure 5 is a sectional view of a damperk plate.

The stove is preferably made ofvsheet metal and is substantially oval in horizontal section, as illustrated, this being the cominon shape of stoves of this character. It comprises essentially three main portions, the top 10, the side wall 11 and the bottom 12 to which the usual supporting legs 13 are secured. These three portions are so secured together as to be readily detachable. As illustrated, screw bolts lll suliicient in number for this purpose are provided, the top having a downwardly extending flange overlapping the upperv edge of the side wall and j thewlbottoin k12 having `an yupwardly eX- tending flange which overlaps the lower edge or theslde wall, the securing bolts 14 extending through theselianges and the side wall, as illustrated in Figure 3.

r1fhe top hasa flanged circular openingk 15 provided rwitha cover 16 and throughtthis opening, when the cover is removed, the fuel may be inserted into thel combustion chamber.,y The top is also provided with a circular opening having a flange lGtowhich the ordinary stove pipe 17 may be fitted inthe usualinanner. c A transverse metallic cur' tain 18 is hung by-suspension rods 19 from the edgeof the ring member 20, which fits closely around the flange of opening 15 and is `not removable with the cover. The purpose of kthis curtain is to direct the draft downwardly against the fuel within the coinbustion chamber, and also to prevent, to a large extent, the products of combustion from passing out through the fuelk opening 15 when the cover is removed to introduce additional fuel. lf desired, the member 18 c may be permanently secured to the top, but

preferably it is detachably hung as illustrated, so as to be readily removable The side wall of the stove is provided with a lflanged opening 21. suitable for connection with a stove-pipe, and `smaller :flanged openings 22 and 23 which are draft i openings. 'ilihen theopening 16, in the top fis connected. to a stove-pipe, as .illustrated in the drawings, the opening 21 is closedby a cover 211 as shown. f

y' ln the drawings, the elbow pipe 25.is con nected tothe flanged opening 22 andL has its upper end open for the free passage of.air, while the lower draft openino 23 is closed by a circular damper plate 26. This damper .T plate 26 lits against the end of the short pipe section or neck 27 which is secured to the flange of the opening23 .and has four spring arms 28 shaped as shown, which press outwardly against the inner wall of the liange and exert a sufficient pressure thereagainst to frictionally hold the plate in position. The damper is freely removable by simply pulling outwardly on the handle, and it is c obvious that a combination of draftsr may be `used if desired by pulling the damper 26 away from its seat a short distance. Although l have illustrated in the drawings only one damper plate, which is interchangelio able with the elbow pipe 25, I may provide two damper plates, one for each opening, by which means any desired combination of draft air feeds to the combustion chamber may be arranged.

The bottom 12 of the stove is, in the present embodiment of my invention, formed in two portions, a lower horizontal plate, and a lire or ash supporting portion formed in two parts 12, 12. rlhese plates 12 slope downwardly toward a longitudinal opening 122 running lengthwise of the bottom plate '12 and the upper edges of these inclined portions are riveted or otherwise suitably secured to the side wall 11. The opening 122 is provided for the removal of ashes and debris through the bottom of thestove and is normally closed by a sliding plate or door 29 which is manipulated by a handle 30. Upon the plates 12 and the sliding door 29 the burning fuel rests and, when the lire is out and itis desired to remove the ashes, it is only necessary' to move the sliding door 29 so that the opening` 122 is uncovered, whereupon the ashes will immediately drop into the receptacle `which has been placed below the stove to receive them, the angle of inclination of the plates 12 being such that the materials on their upper surfaces will slide down when unsupported from below. Hand holes 123 are formed in plate 12 so that the bolts .14 securing the sections together may be easily reached.

Although l have described and illustrated the portions 12of the lire bottom as secured to the side wall, it is obvious that they may be conveniently secured in other ways, and as other changes may obviously be made in the arrangement of parts l. do not limit myself to the exact form described and illustrated. The adjustability of the draft, the adaptability of the stove to dill'erent positions because of the fact that the stovepipo may be connected to the top or side, the sectional construction, whereby any section burned out or otherwise injured may be replaced without involving tlie replacement of the whole stove or any other section, and

the vconstruction which enables the user to quickly and conveniently remove the ashes V the stove particularly useful from a prac#y tical standpoint.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1.111 a stove of the class described, in combination, a combustion chamber y elongated in horizontal cross section, such chainber having van opening in its top'y forl the introduction of fueland a longitudinal central slot or opening in its bottom for the removal of ashes, two flat fuel. supporting plates eX- tending longitudinally of said chamber one on each side of said openingand inclined downwardly toward the same, andan elongated sliding doorfor controlling the passage of ashes through said opening.

2. ln a stove of the class described, in combination, a combustion chamber having an elongated horizontal cross section, said chamber having an opening inits top for the introduction of fuel and a central longitudinal. slot or opening in its bottom for the removal of ashes, two flat fuel. supporting plates extending longitudinally of said chamber' one on each side of said opening and inclined downwardly toward the same, the inner edge of the plates terminating at the edges of the central opening, and the outer edges of the plates being' secured to the side walls of the chamber, and anelongated sliding door for controlling the passage of ashes through said opening.

ln a stove of the class described, a body comprising a top. side wall and bottom, and having air inlet openings in. the side wall adjacent the top and bottom respectively, and a damper pl ate adapted to Atit either of said openings asdesired to close the same.

ln testimony whereof l allix my signature.
